There are wines from California that Pirlo would no doubt love, but you have to know about them to find them, and that takes a lot of research (which basically means drinking, which is no hardship, believe me). I like Napa Cabs, but hardly ever buy them because they are way too expensive for what you get. There are some wonderful pinots from across the mountains in Sonoma, and I found a producer of old vine zinfandel that I buy, but I am more likely to go with something esoteric from Europe. It's really just pricing. If you know where to look, you can find something that is just as good or better for 1/5 the cost of the wines from Napa. Same is true of Bordeaux.
